Write Timing (using R/W, CS0-controlled)
Figure 32 shows the write-timing behavior when the WR(R/W) input is programmed as a combined read-write input
R/W. The RD input has to be tied to high-level in this configuration. This timing is called CS0-controlled because CS0
is the last external signal of CS0, CS1, and R/W which becomes valid. The writing to the THS1209 can be performed
irrespective of the conversion clock signal CONV_CLK.
